Science China Press A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough. It is tesitfied that the continental shelf of the East China Sea was exposed and covered with the huge wetland and grassland ecosystems during the the last two glacial periods. They discovered that the variation of terrestrial sources is concordent with global glacial volume and sea-level changes at...

The terms “gas” and “sea” for many will invoke associations of reserves, business, and a lot of money. Whatever the association, most of the efforts in Israel´s energy field are being directed at gas buried deep under the Mediterranean seabed. Now a new geophysical study, the first of its kind in Israel, has uncovered a system of active gas springs in the Haifa Bay seabed, at relatively shallow depths, only a few dozen meters below the surface. The study,...

Marine scientists from five research agencies have pooled their skills and resources to compile a directory of life on Australia's continental shelf. They examined the shelf seascape during a three-year program of the Commonwealth Environment Research Facilities (CERF) Marine Biodiversity Hub. Hub director, Professor Nic Bax of CSIRO and the University of Tasmania, says the program developed and applied a consistent, national approach to biodiversity mapping. "The program compiled existing...

A study led by Dr Stuart Painter of the National Oceanography Centre helps explain the formation of huge phytoplankton blooms off the southeast coast of South America during the austral summer (December-January). The region supports the highly productive Patagonian Shelf marine ecosystem, which includes a globally important fishery. Coccolithophores are key members of the marine phytoplankton community. They are abundant in the sunlit upper layer of the world's oceans, often forming vast...

Scientists from the United States and Canada have announced plans to embark on a joint expedition to map the Arctic seafloor this summer. The expedition, which was announced via a July 26 press release, is set to begin today (August 2) and will run through September 6. The five-week mission marks the third straight year that the two North American nations have collaborated to study the Arctic seafloor and the continental shelf. According to the press release, one main focus of the expedition...

Underwater canyons have long been considered important habitats for marine life, but until recently, only canyons on continental margins had been intensively studied. Researchers from Hawaii Pacific University (HPU) and the University of Hawaii at Manoa (UHM) have now conducted the first extensive study of canyons in the oceanic Hawaiian Archipelago and found that these submarine canyons support especially abundant and unique communities of megafauna (large animals such as fish, shrimp,...

Reductions in the flow of the Apalachicola River have far-reaching effects that could prove detrimental to grouper and other reef fish populations in the northeastern Gulf of Mexico, according to a new Florida State University study that may provide new ammunition for states engaged in a nearly two-decade water war. The Florida State researchers found that in years with low river flow, the concentration of phytoplankton -- the microscopic plant-like organisms that feed into the food chain --...

A U.N. deadline on May 13th over maritime boundaries will attempt to solve disputes over the seabed from the South China Sea to the North Pole, Reuters reported. A U.N. Commission that aims to set limits for national rights to everything from oil and gas to life on the ocean floor is asking most coastal states to define their continental shelves (areas of shallower water offshore) by Wednesday. Harald Brekke, a Norwegian official who is a vice-chair of the U.N. Commission on the Limits of the...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
